Patented Apr. 25, 1933 UNITED STATES JOE MANZI'ITO, OF NEBRASKA ELECTRIC HEATER Application filed May 5, 1932. Serial no. 609,481.

The invention relates to electric heaters of portable nature designed for heating small private garages but applicable to other uses, and it consists in the novel construction and 5 combinations of parts as set forth in the appended claims.

In the accompanying drawings illustrating the invention Figure 1 is a top plan view of the heater.

Figure 2 is a section on the line BB, Figure 1.

Figure 3 is a detail top plan View of the fire-bond plate and the electrical resistance elements.

Figure 4 is a section on the line AA, Figure 5.

Figure 5 is a detail side view of the fire bond plate and its supports.

Figure 6 is a detail bottom plan View of the fire-bond plate.

In these drawings the numeral 1, designates a metal drum of circular form in cross section, having horizontal top and bottom 2 and 3, legs 1, and spaced top openings 5, the latter engaged by heated air outlet pipes 6 of elbow form and turned permanently in different directions for better heat distributing purposes as will be explained.

Intermediate of the height of the drum and J within the same is located a planular square horizontal fire-bond plate 7, located at its corners close to the inner wall of the drum and spaced from the same at top, bottom and sides thereof, the side spaces being of sector form as shown at 8. Supporting means are provided for said plate consisting of upright rods 9 connecting top and bottom of the drum and carrying tubular insulation elements or tubes 10 engaging the top and bottom of the drum and the top and bottom of said plate.

Means are provided to heat the fire-bond plate 7 comprising four resistance coils 11, electric circuit wires 12 having one terminal connected to the first coil, at binding post 13, Figure 6, extending transversely through said plate to said coil, binding post 14 being connected with the opposite end of the coil and similarly extended transversely through said plate to the opposite side thereof where it is do connected with the other circuit wire by short wire 15, thereby forming a complete and independent circuit through this coil. The second of the coils 11, is connected at 16 with the first or positive circuit wire and the opposite end of the coil is connected with binding post 17, both binding posts 16 and 17 extending transversely through plate 7, and the last named post being connected to the other or negative circuit wire by short wire 18, thereby forming a second complete and independent circuit through the second coil, the two circuits being in parallel so that if one of the coils should burn out, the other will still remain in heating action.

The othertwo coils 11 are similarly connected in parallel with the electric circuit Wires and'with the first two coils and for the same reason, the respective binding posts being designated 19, 20 and 21, 22, and respech tive short wires completing the circuit 23 and 24. The fire-bond plate 7 is recessed in its top face in accord with the shape of the coils which are received in said recesses with their top surfaces substantially flush with the top surface of said plate.

In operation the fire-bond plate 7 is heated to incandescence thereby heating the drum and the air contained therein, cool air entering the drum through lower openings 25, the

form spaces between the sides of the said plate and the drum through which the air rises to the upper part of the drum. From the upper part of the drum the heated air passes through the top openings of the drum to and through the tubular elbows 6, which act as further baflies to retard the escape of the heated air, and being turned permanently in different directions discharge the heated air accordingly, thereby facilitating the heating 7 effect upon the garage or inclosure being heated.

The invention is adapted for ready and economical assembly and operation and is readily transportable by means of the handles 26 attached to the drum top, the entire device 00 being quite light in weight. The drum may be made in separable sections or joints telescoping or otherwise separably connected so that access may be readily had to the firebond plate and the resistance coils, and the parts may be readily assembled.

I Obvious changes may be made Without departing from the spirit of the invention stated in the claims.

I claim I 1. In an electric heater, an upstanding metal drum. a horizontal planular fire-bond plate located Within said drum intermediately of the height thereof and spaced from the interior drum Wall at the top, bottom and sides thereof, means for supporting said plate including upright rods connecting the top and bottom of the drum and carrying tubular insulation elements engaging the top and bottom of the drum and the top and bottom of said plate, electric means for heating said plate, said plate acting as a bafiie for rising heated air in the drum. said drum having top openings, and tubular elbows engaging said openings and turned permanently in different directions, said. elbows acting as further battles for heated air and discharging in different directions to further facilitate the heating effect.

2. In an electric heater, an upstanding metal drum, of circular form in cross section, a horizontal square planular fire-bond plate located Within said drum i'ntermediately of the height thereof and spaced from the interior drum Wall at the top, bottom and sides thereof, the side spaces being of sector-form, means for supporting said plate including upright rods connecting the top and bottom of the drum and carrying tubular insulation elements engaging the top and bottom of the drum and the top and bottom of said plate, electric means for heating said plate, said plate acting as a bafile for heated air, said drum having top openings, and tubular elbows engaging said openings and turned permanently in different directions, said elbows acting as further battles for heated air.

In testimony whereof I affix my signature.

JOE MANZITTO.
